Closest alternative with matching technology, tolerance, and TCR in the same 0402 package.
Best Alternatives to FRC0402F1691TS
Finding a replacement for the FRC0402F1691TS involves selecting from several 0402 chip resistors with slightly different resistance values. Key alternatives include parts with very close resistance like the FRC0402F1651TS (1.65kΩ) or high-precision upgrades.
AI replacement insight
Electrical risklow
Resistance values are within 10% for all candidates. Tolerance and power ratings match or are better.
Package risklow
All candidates use the same 0402 package, ensuring form and fit compatibility.
Sourcing riskmedium
The target's non-standard value may be difficult to source. Alternatives are standard, widely available values.
Can it be replaced directly?
Direct replacement for FRC0402F1691TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
For a near drop-in replacement, FRC0402F1651TS offers the closest resistance (1.65kΩ) and identical technology. For an upgrade in precision, consider the thin-film RT0402BRD071K65L.
Main risk
The primary risk is the deviation in resistance value, as the target's 1.69kΩ is non-standard. A secondary risk involves changing from Thick Film to Thin Film technology, which can affect circuit performance under specific conditions like high-frequency or pulse loads.
